It seems that CNAME is not a popular UniBasic command.  Is there some
history here I'm not aware of, maybe it was unreliable?  

>From a UniBasic program, why would you open a file, read a record, write
it back to the same file under a different key, then delete the original
record, when you could just:

  X.CMD = "CNAME filename ":X.ID:',':X.NEW.ID
  EXECUTE X.CMD

No changes to the data are required.  For example, if a bunch of records
get written with the wrong date embedded in the key.

This situation came up on info-datatel.  Here, it happens so rarely that
it's barely worth worrying about-- I'm just curious.
